Ali Ouedraogo, 38, was killed while praying behind the counter at the convenience store where he worked in Baltimore on December 14, 2017. A bullet came through the store wall and struck him in the head; he was found lying face-down. The shooting was described as part of a wider, apparently random rampage that unfolded across December 14 and 15.

Authorities say the attacker, Mausean Carter, shot eight people at random over those two days and also killed Martell Harris at a food market. The spree ended after a 50-minute high-speed pursuit in which Carter fired at officers and civilians and wounded additional people before being taken into custody. A jury later found Carter guilty of first-degree murder in Harris’s death and convicted him on multiple attempted murder and handgun counts related to the shootings and chase; he was sentenced to two life terms plus 60 years after a trial that rejected a plea of not criminally responsible.

If anyone worked at or near those locations in December 2017 or has information that could add detail about Ali Ouedraogo’s final hours, please come forward.
